I am finally getting my backyard fenced.. doing it myself after work so it's going to be another few weeks.

I was just curious what kind of toys or apparatus for outside entertainment is available to buy or make.. I will make a flirt pole but was also wondering if there was something that would keep her busy enough that I could maybe leave her at home for a few hours at a time. At this point she goes everywhere with me and waits in the car while I am working.
